Mr. Blasberg chooses the top 10 chicest looks from the week.

I have to be completely honest here: I’m at the beach and I may have slightly slipped on my political news. So I had no idea what Beyoncé was doing at the United Nations this week. I do know, however, that she looked drop-dead gorgeous in this form-fitting Alexander McQueen blouse and skirt. Which begets a certain theory I’m surprised I haven’t thought of before: Perhaps if everyone at the UN looked this divine, we could get a lot more done.

Hanne Gaby Odiele in Prabal Gurung for ICB

I wish I knew what goes through Hanne Gaby’s mind when she gets dressed in the morning. You never know what you’re going to get with this one: I’ve seen her in culottes, unitards, latex, and everything in between. Not that I’m complaining. Along with just about every other street-style blogger in the world, I can say that she is one of the most stylish models in the business today—even when she’s cleaned up and wearing something more traditional, like this Prabal Gurung for ICB dress, which she wore to a party celebrating the collection in New York.

Kate Upton in Antonio Berardi

I have an older brother who keeps me plugged into sports things, and he was the one who first told me about Kate Upton. I think it had something to do with a certain Sports Illustrated cover and an incredibly disappearing bikini bottom. But what I like about Kate is that, while she can work thongs and teeny tiny tops with aplomb, when she’s left to her own devices her style skews much more classic. I love this simple red Antonio Berardi dress. She’s still a total sexpot, of course, but not in such an overt way. (For the record, I’m not sure my brother would prefer this to that swimsuit.)

Lady Gaga in Hermès

Lady Gaga hasn’t popped up on my best-dressed list for awhile, and I have to say I’ve missed her. (I also have to say that it was good she took some time off so we all had some time to miss her.) But she’s back, and she’s back to her old tricks. This is what she wore around Sofia, Bulgaria recently. I’m not sure if I understand it— that dress didn’t have a gas mask when it was shown on the Hermès runway— but it’s entirely eccentric and it’s entirely her. Besides, I like any look that’s accessorized with a cute little puppy.

Gwyneth Paltrow in Los Angeles

Apple’s mom and the original apple of my eye, Gwyneth Paltrow, hit California this week, and she brought her best West Coast looks with her. I loved this cream sweater, and apparently she did too, since she wore it two days in a row—first with jeans and then with these short shorts. And doesn’t she look radiant? I chose this look in particular because Gwyneth made me do something I thought would never be possible again: rethink the white sunglasses. Hey, she looks cute in them.

Jessica Biel in Giambattista Valli

I know, another week, another Jessica Biel shout-out. This is the third time in three weeks! So I’ll say what I said last week: I was never blown out of the water by Jessica’s subtle style, but she’s been knocking them out of the park on the Total Recall press tour. There was the sexy Mugler and the fabulous Dior couture, and now there’s this screen-siren Giambattista Valli couture dress she wore in London. Bonus points for the pop of pink with those Christian Louboutin shoes.

Eva Longoria in ASOS

When I was a kid, my mother used to tease people who looked cheap by describing them as someone “who could make silk look like polyester.” (It’s a good line, isn’t it?) Well, Eva Longoria is the complete reverse of this. Here is the actress and part-time restaurateur, leaving her eatery, Besos, in L.A. in a tight red ASOS dress. ASOS is what we like to call an affordable fashion house, ladies. But Eva makes it look like a million bucks. Sadly, the same can’t be said for those Charlotte Olympia platform heels. Those will set you back a few pennies.

Blake Lively in Roland Mouret

Speaking of girls in tight sexy dresses, on the other side of the country Blake Lively was heading to her Gossip Girl set in an equally vampy cocktail dress from Roland Mouret. What I like about Blake Lively is that she’s a real American girl. The big hair, the bustline, the giant smile: She’s living the American Dream.

Viola Davis in Vivienne Westwood

I just love Viola Davis, and I have for years—well before The Help, I feel like I should say. And I love it when she gives herself a little push in the style department. Especially as most serious women in Hollywood don’t necessarily consider best-dressed lists like this one to be that big of a deal. (How dare you, Viola!) But she looked divine in this bright, white Vivienne Westwood shift dress with its subtle draping and side pleating.

Robert Pattinson in Gucci

Robert Pattinson has just joined a very short list of well-dressed men who have inched out their female counterparts to make an appearance on the best-dressed list. (Only the Brant brothers and Kanye West have preceded him.) But when I saw him at the premiere of his new film, Cosmopolis, in this blue Gucci suit, I thought he deserved it. Not just because he’s devastatingly handsome—which I don’t think anyone needs to hear from me—but also because I think he’s a standup gentleman to fulfill the promotional obligations for his movie despite the, umm, slightly public personal situation he’s going through with Kristen Stewart. I’m sure it would have been easy to have a publicist cancel everything, and people would have understood why. But he’s doing it, and he’s looking damn good while he’s doing it. That reminds me: Did anyone see him on Jon Stewart this week? He looked absolutely adorable. In another Gucci suit, actually.
